This is an example of using Play framework to implement the GET method for submitting search queries.
The URL http://localhost:9000/search
will give you the search box.
Upon on clicking the search button, the browser will append ?q=<whatever search query that was entered>
to the URL and refreshes the page.
The new URL after submission will be http://localhost:9000/search?q=<whatever search query that was entered>
and play framwork renders the result page as defined in the controller.
